[Japan: Many years ago.]
Whooosh.
A huge explosion rocked the training building as two young girls clashed their swords against each other.
One had a red aura that seemed to emit a certain heat while the other one was covered in wind and faint spark lightning.
The ground was covered in craters of varying depth and width and all around, people were observing the fight with nothing but awe in their eyes.
In the end, the red aura faltered and was completely crushed by the might of the other one.
"Ooohh! Good job young lady!"
"Show that mad mutt who is the boss!"
Cheers rang as the witnesses cheered the victory of the heiress. Clearly, they were happy to see the current result.
When the dust finally dissipated, they could see the black-haired young girl holding her sword over the throat of the crimson-haired girl.
